Abstract :
Oncocytic Schneiderian papilloma is a rarely seen benign tumor, which originates from the sinonasal respiratory epithelium, due to the proliferation on oncocytes. A unilateral nasal obstruction or nasal polyp usually leads to such a case and can mimic several other lesions, making its diagnosis challenging. The Histopathological analysis of this case would be able to rule out other potential diagnosis due to the inconclusiveness of the imaging investigations. Surgical excision remains the primary treatment approach, with a favorable prognosis and low recurrence rates. And increased awareness of the characteristics and understanding of this entity will facilitate prompt diagnosis and appropriate management in clinical practice.
We present a case of oncocytic Schneiderian papilloma originating in the nasoethmoidal region, which extends to the intracranial skull base through a bone dehiscence, with involvement of both the intradural and orbital spaces. Surgical treatment is the primary approach, and the endonasal endoscopic technique has proven to be the both effective and safe, even in cases with extension beyond the nasal cavity.
